Phase & Neutral Balancing Systems a three-phase system, which is installed at the low voltage supply line between phases and neutral i.e., parallel to the impedance. PNBS due to its magnetic symmetry tries to establish neutral point symmetrical with respect to the phase voltages. Thus, it equalizes the voltages in all the three phases and minimizes the neutral current.

Insurance against neutral break :
Due to any break in neutral connection, a consumer gets 415 Volts instead of 230 volts. This damages most of the electrical, electronic, telecom equipment and household appliances. PNBS continues to provide neutral, protecting valuable equipment / appliances against any such damages.

Capacity of PNBS :
Capacity of PNBS In a balanced three phase system the current flowing through the neutral should be zero. However, it is practically not possible to distribute & ensure equal loading of each phase. Uneven loading on the phases, causes unbalanced phase voltage, phase distortion and excessive current flowing through the neutral, which results in loss of energy. PNBS corrects this situation. In a balanced Three phase system the current flowing through the neutral should be zero. However, it is practically not possible to distribute & ensure equal loading of each phase. Uneven loading on the phases, causes unbalanced phase voltage, phase distortion and excessive current flowing through the neutral, which results in loss of energy. PNBS corrects this situation. The PNBS equalizes the phase voltage, maintains phase angle symmetry and minimizes the neutral current. The capacity of PNBS is therefore defined in terms of its ability to correct the error measured in terms of the neutral current. The capacity of the PNBS required is dependent on the situation, at a particular location.
